Tennis Explained: Scoring, Rankings, Surfaces

Section 01

How a match is won

Four nested containers. That’s the entire structure.

Tennis is not one long contest. It is a stack of small ones, and you only ever need to win the current small one. This is why a player can lose far more points than her opponent and still win the match.

The stack

Point

One rally

From the serve until somebody misses. The smallest unit.
Game

Four points, win by two

One player serves the entire game. Next game, the other serves.
Set

Six games, win by two

So 6–4 ends a set, but 6–5 does not — you play on to 7–5. At 6–6 you play a tiebreak (Section 03).
Match

Best of three sets

Women’s tennis plays best of three — first to win two sets wins, so a match ends 2–0 or 2–1 in sets.

The thing nobody tells you Points don’t carry over. Lose a game 0–40, and the next game starts level at love–all. Every game is a fresh sheet — which is exactly why comebacks happen and why you should not turn it off.

Section 02

Why the score sounds insane

15, 30, 40. There is no 45. Nobody knows why for certain.

Within a single game the score is called in a sequence inherited from centuries of habit. You do not need to justify it. You need to recognise it.

Reading a game

0 points

“Love”

0–0 is called “love–all.”
1 point

“15”

The server’s score is always said first.
2 points

“30”

—
3 points

“40”

One point from winning the game — if you’re ahead.
40–40

“Deuce”

Tied at three points each. Now somebody has to win two points in a row.
After deuce

“Advantage”

Win one point from deuce and you have advantage. Win the next and the game is yours. Lose it and it goes back to deuce — which can repeat for a very long time. This is the single most stressful thing in the sport.

Vocabulary that actually matters A break is winning a game your opponent served. Serving is an advantage, so holding your own serve is expected and breaking theirs is how you actually get ahead. When the commentator sounds excited about “break point,” that is why.

Section 03

The tiebreak

What happens at 6–6, and why the final set is different.

A set can’t go on forever, so at six games all the set is decided by a tiebreak — a single sprint to a number, counted in ordinary 1, 2, 3 rather than 15/30/40.

Two kinds

Normal set

First to 7 points, win by 2

Played at 6–6. If it reaches 6–6 inside the tiebreak, it continues until someone leads by two — so 9–7, 12–10, and worse, happen regularly.
Final set

First to 10 points, win by 2

At the four Grand Slams, a deciding set tied at 6–6 is settled with a 10‑point tiebreak. The majors standardised this in 2022 — before that, each ran its own rule.

Watch for A mini‑break is winning a point inside the tiebreak on your opponent’s serve. In a tiebreak, one mini‑break is usually the whole difference.

Section 04

Not all wins are equal

What the tournament tiers are, and what winning one is worth.

Every event carries a points value, and the tiers are named for roughly what the champion earns. This is why beating a top player at a small event moves the ranking less than a deep run at a big one.

The tiers, champion’s points

Grand Slam

2,000 points

The four majors: Australian Open, Roland-Garros (French Open), Wimbledon, US Open. The biggest events in the sport.
WTA Finals

up to 1,500 points

Year-end championship for the season’s best qualifiers. An undefeated champion takes the maximum.
WTA 1000

1,000 points

The tier below the majors. Miami, Indian Wells, Toronto/Montreal, and others.
WTA 500

~470–500 points

Solid tour-level events. Alex Eala’s Washington title was at this tier.
WTA 250

~250–280 points

The entry rung of the main tour.

Note The 500 and 250 figures are ranges because the WTA adjusts exact values. Treat the tier names as the reliable part and the precise number as approximate.

Section 05

How the ranking actually moves

The part that confuses everyone, including people who have watched for years.

A WTA ranking is not a career total and it is not a season total. It is a rolling 52‑week window: the points you earned over the last year, added up. Results older than about a year fall out of the calculation entirely.

The mechanics

Window

Rolling 52 weeks, cumulative

Always the last year, updated weekly. Never the whole career.
Count

Up to 18 tournaments

19 if she played the WTA Finals, which counts as a bonus event on top.
Required

The big ones are compulsory

The window must include the four Grand Slams, six WTA 1000 Mandatory combined tournaments and one WTA 1000 Mandatory (WTA‑only) — then the best seven results from everything else.
Defending

Last year’s points expire

When a tournament comes round again, the points she earned there last year drop off. Match that result and she stands still; beat it and she climbs; lose early and she falls — even having won nothing bad this week. This is what “points to defend” means.

Ranking vs. Race — two different tables The Ranking is the rolling 52‑week list above — the famous one, the “world No. 20.” The Race counts only points earned since January of the current calendar year, and it decides who qualifies for the WTA Finals. A player can sit high in one and lower in the other. They are not in conflict; they measure different things.

Section 06

The three surfaces

Why the same player looks like two different players in April and July.

Hard

Medium-fast, predictable bounce

The most common surface and the bulk of the calendar — including the Australian and US Opens. Rewards clean, aggressive hitting.
Clay

Slow, high bounce, long rallies

The European spring, ending at Roland-Garros. Players slide into shots. Rewards patience and stamina; punishes anyone hoping to end points quickly.
Grass

Fast, low bounce, short season

A few weeks in early summer, built around Wimbledon. Points end fast and the serve matters more than anywhere else.

Why it matters A ranking is one number across all three. Form is not. “She’s a good clay-courter” is a real statement, not commentary filler.

Section 07 — the clock

Why it is always 3 a.m.

Manila runs on Philippine Standard Time, UTC+8, with no daylight saving — the offset never changes, which at least makes the arithmetic stable. Most of the tour is in Europe and North America. A tournament in New York playing a comfortable evening session is playing it in the small hours of the following Manila morning; a European afternoon lands in the Philippine evening or late night.

Nothing is wrong with your stream. The sport is simply on the other side of the planet, and the reason this site exists is that the entire country keeps choosing to be awake for it anyway.

Section 08

Glossary

Terms you will hear in the first ten minutes of any broadcast.

Ace

A serve the returner never touches

Instant point.
Double fault

Both serve attempts miss

You get two chances to serve. Miss both and you hand over the point.
Hold / break

Winning your serve / winning theirs

Breaking is the hard one, and the one that decides sets.
Unforced error

A miss nobody forced

Distinct from a winner, where the opponent earned it. Commentators keep score of both.
Seed

A ranked, protected entrant

The best-ranked players in a draw are seeded so they can’t meet each other in round one.
Qualifier

Played in through a pre-tournament draw

Won matches just to reach the main draw.
Wildcard

Invited by the tournament

Entry granted rather than earned by ranking.
Retirement

Stopping mid-match, usually injury

Different from a walkover, where a player withdraws before play starts.

You are now qualified to watch

That is genuinely all the theory required. The rest is staying awake — and the clinic can document that for you.
